It's exactly what it says on the tin, and it's incredible. I spent more time on this than I'd like to admit - the mechanics are incredibly satisfying, and remind me of something that I would have found on coolmathgames as a kid (in the best way possible). The sound design is fantastic, too, and really makes you feel like you're whackin some blocks with a pickaxe. Overall an incredible experience and one that I will be recommending to several friends!
